SPECIFICATION forming part of Letters Patent No. 639,153, dated December V12, 1899. Application filed August 16, 1899. Serial No. 727,379. (No model.)

The pod B, havinga depending leg h to be struck by the lay as it beats up, is secured to lor forms a part of the outer end of the shank B', and it has a recess to receive a rounded shoulder 7 of the cap F, which latter is mounted to rock on a pivot b2 which, as herein represented, also forms a supportfor the cylindrical toothed roll R. v

Referring to Fig. 2, the cap is shown as provided at its inner side with a rearwardly-extended earfX, between which and the top of the adjacent part of the shank is interposed a spring S5, which lifts the ear and tips the cap on its fulcrum h2, to depress the outer edge f of the cap. A headed and preferably screwthreaded stud 40, passed loosely through the ear and into the stand, acts as a stop to limit the spring-induced movement of the cap.

The cloth passes between the edges of the cap and pod, over the toothed roll, and out beneath the edge f of thecap, the lifting tendency of the cloth to separate from the teeth being yieldingly counteracted by the spring S5. The pivot b2 is shown as extended through from one to the other end of the pod and threaded at h4 to enter a threaded hole in the upturned end b5 of the pod, the roll being rotatably mounted on said pivot.

Vire have herein shown the roll as comprising a body portion, a plurality of detachable toothed blades, and means to retain the blades in place on the bodyportion, the latter being shown as a cylinder r, longitudinally bored to receive the pivot h2 and having its ends reduced, as at r', and exterior-ly threaded. (See Fig. It.) Longitudinal grooves or seats are made in the body to receive each a toothed metal blade r2, the blades having their ends notched, as at r3, (see Fig. 6,) the blades being substantially as long as the body, exclusive of its reduced ends r. yRetaining rings or collars r4, having on their inner faces annular ribs r5, are slipped onto the extensions r of the body portion and against the ends of the blades, the ribs r5 entering the notches r3 of the latter to hold the blades in position on the body, and t'o prevent removal of the rings or collars nuts r6 are screwed upon the extensions r' up snugly against the rings, thereby lirmly holding the blades in place, yet permitting of their ready removal should one or more teeth of a blade or blades become bent or broken. In such event the notches and rings or collars are loosened suciently to permit the Withdrawal of the injured blade and a new 'one is inserted, after which the blade-retaining devices are secured in place.

The Inode of construction of the roll obviates the accurate construction and machining necessary Where the teeth are inserted sepa- `rately.

Having fully described our invention, what We claim, and desire to secure by Letters Patent, is

l. In a loom-temple, a stand, a tem ple-head having a shank longitudinally movable in the stand,a spring to normally maintain the shank extended, a controller for the latter, operative through the spring to maintain the head in operative position, or retracted, and a lock to retain the controller in normal position.

2. In a loom-temple, a temple-head having a shank, a stand in which the shank is longitudinally movable, a spring connected at one end with the shank to normally maintain the head in operative position, and a controller pivotally mounted on the stand and connected with the other end of the spring, the controller when in normal position subjecting the spring to tension to retain the shank extended, and when in abnormal position operating through said spring to maintain the shank retracted.

3. In a loom-temple, a temple-head having a longitudinally-slotted shank, a stand provided with a guide for and in which the shank is reciprocable, a pivoted controller mounted on the stand and depending through the slot in the shank, and a spring attached at one end to the depending part of the controller and at its other end to the rear end of the shank,

the controller in normal position stretching the spring to maintain the shank extended, movement of the controller into abnormal position acting through the spring to retract the shank.

1t. In a loom-temple, a temple-head having a longitudinally-slotted shank, a stand provided With a guide for and in which the shank is reciprocable, a bent lever pivoted on the stand and having one arm extended through the slot of and below the shank, a spring connecting said arm and the rear end of the shank, and a springlatch to engage the other lever-arm and maintain it in normal position with the spring under tension, to extend the shank, release and shifting of the lever `acting through the springto retract the shank.

5. In a loom-temple, a stand, a temple-head having a shank longitudinally movable in the stand, a 'spring attached at one end to the rear end of the shank, and a movable member mounted on the stand between the temple-head and the rear end of the stand, to which the other end of the spring is attached, movement of the ,said member subjecting the spring to tension or compression, to thereby extend or retract the shank, respectively.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
